The USP here is the quality of eye care: Michel Guillon provides a comprehensive service that includes extra eye checks and nutritional advice. Drawing on 25 years of scientific research, Guillon is an expert in contact lens research, providing lenses for people normally unable to wear them. Sporty types too can benefit from the shop’s dynamic vision testing, designed to improve visual reactions. The Ab Rogers-designed interior is a hint at the high-tech service available here: striking blue cabinets house a changing range of designer frames that includes Japanese Yellows Plus and elegant Gold & Wood (spec providers to the stars), as well as Guillon’s own brand.
